Are they teaching sex-ed too young?

I was sitting at the dinner table with my boyfriends family and his little brother, that is in 5th grade, was talking about what he learnt in sex-ed. He told us that they got to put condoms on bananas, the problem is, now he keeps talking about wanting to put condoms on his own pen*s. We are afraid that hes going to go out and experiment now. I'm glad that he wants to be protected but hes simply way way way to young to be even thinking about having sex.
I understand that kids do need to be taught about sex, but do you think it sort of encourages them a bit to try it out? He was never like this until they got to put a condom on a banana.
Just wanted to know your oppinions on this.
Because personally I think they are going the wrong way abouts educating kids about sex.

Also, does anyone know how we could maybe go abouts getting him out of this phase?

Alright, thanks for the advise.
Yeah, I again, do agree they do need to get educated about it early. It just kind of had us worried, but hopefully he wont experiment yet.

He's probably just over-excited because it's a novelty.

honestly when you hit 6th grade aka middle school, that is where ALL the trouble starts about sex rumors and discovering the street meanings of 'blow jobs' and 'popping the cherry' and THAT is what will make kids want to experiment, and some might actually do it. so I believe 5th grade is the perfect year to start being aware of the dangers of sexual intercourse, and the precautions that you should take because when middle school starts, so do all the false rumors about sex. I'm sure you've even seen it on this site where 12 year old little girls ask something silly that they've heard from others like 'he told me that if masturbates before we have sex his sperm will be empty, is that true??!11?!' I don't think those girls had the privilege of learrning about that stuff in elementary school, as most elementary schools don't participate in that.

I got a sex ed both on 6th and 7th grade, a friend of mine actually passed out. lol. but well, none of us tried, but its really good to know how baby's are made and all, but they didnt really teach us specifically about sex.. they taught us about periods sperms and how babys grow in your tummies..
so I think it both has advantage and disadvantages..
and parents should help too, with the talking and stuff, maybe specify it more..

well I was taught at around 5th grade either... teach him about the other things about sex he will probably think its nasty and get out of the phase lol and as for do I think he is too young. no of course not cause what if he does learn it from a friend or something and if he wants to try it also then he is not ganna no to proteact himself and end up in a tough situation ... hope I helped ~kaitlyn~ oh and for tina todder no a guy is not 'empty' after mas*erb*ting

Look at the questions on here like: 'can I get pregnant by humping a pillow'. Seems like there is not enough education to help the kids that want to know whats going on. I'm not a fan of starting it in the 5th grade, because some kids think that if you are told what to do, you should go right out and do it. But I do think kids are severely uneducated on the subject which gets them into major trouble.

I don't think kids should have sex till like 16...but its never to ealie to tech sex ed...becuase they won't stop trying it out...I mean kids are getting preg at age 10!!!
